The 34-year-old, formerly or Newcastle Eagles and most recently Leicester Riders, joins the Londoners on a two-year deal.

Lions have already signed last season’s MVP Zaire Taylor from Worchester Wolves as well as Makal Stubbins who was playing in Egypt.

And Sullivan, who is a two-time BBL League MVP, is excited about returning to the city of his birth.

He said: “I feel like it’s a long time coming and when [London Lions coach] Vince [Macaulay] offered me the chance to join the Lions I bit his hand off”

Family was also a big factor in Sullivan’s decision in to move back to London.

He added: “Returning to London means I can see more of my family and also having some home cooked meals from my mum.”

Asked which player he is particularly excited about linking up with, he said: “I am looking forward to playing alongside Zaire Taylor, who for me is similar to me with his burning desire to compete and win.”

A visibly ecstatic Macaulay said: “Andrew was our number one target this summer and we are hoping Drew can have the same impact at the Lions then at all other clubs he played at.”

Before starting life with London Lions, Sullivan is captaining Great Britain on Wednesday at the Copper Box for the second EuroBasket qualifier against Bosnia and Herzegovina.
